• Producția științifică a institutului, pe un curs calitativ și cantitativ ascendent

Prin valoarea specialiștilor săi și a productivității științifice, Institutul Național pentru Fizica Laserilor, Plasmei și Radiației (INFLPR) de la Măgurele este unul dintre cele mai mari entități de cercetare și dezvoltare din România, reușind în ultimii ani să se plaseze tot mai pronunțat în fluxul principal de cunoaștere. INFLPR îşi consolidează recunoaşterea pe plan mondial prin implicări în colaborări internaţionale semnificative, precum Laserlab, în domeniul laserilor, şi Euratom, în domeniul plasmei şi radiaţiei, dar şi prin lucrări ştiinţifice de o calitate remarcabilă, recunoscute şi promovate de mediul academic, ştiinţific şi tehnologic.

În perioada 2009-2020, INFLPR a realizat peste 4.780 lucrări ştiinţifice, înregistrate în baza de date Web of Science (WoS), în creştere permanentă, totalizând peste 79.000 citări şi un index Hirsh instituţional mai mare de 100.

Abstract: In the last year, our X-ray tomography laboratory extended its portfolio by commissioning a new high penetration power X-ray microtomography system. This led to new opportunities in the research domains that were prior difficult to tackle, such as high X-ray attenuating samples from the metallographic industry.
The main objectives of this study consisted in the development of several methodologies aided by the industrial X-ray tomograph and designed to assist the additive manufacturing process. Thus, during this work we addressed high and low attenuating samples at different manufacturing stages.
Metallic powders and bulk samples used in the additive manufacturing with high-power laser were analyzed from qualitative and quantitative point of view. To offer an alternative to the limited classical metrological methods, the X-ray tomography instrument has been used as a method of rapid prototyping by iterative comparisons between the initial CAD model and the 3D model of tomographic reconstruction. This provided the opportunity to assist the restauration of industrial components by laser cladding via X-ray tomography, considering the fact that the CAD model serves as input data for the laser processing.
Advanced image protocols for defectoscopy and metrology processing were performed by implementing different algorithms from the main commercial software packages: VGstudio Max and Avizo. A 3D printer was used for manufacturing of polymer test samples with varying filling grades that were further evaluated by the mentioned algorithms. Also, visual comparisons were made between the virtual sections obtained by 3D reconstructions and the optical images extracted by destructive analysis.

The E-MRS 2020 Spring Meeting at the foreseen dates (May 25-29) is CANCELLED and has to be POSTPONED.

There is a growing interest towards pulsed methods like High Power Impulse Magnetron Sputtering (HiPIMS), Pulsed Laser Deposition (PLD), Pulsed Electron Beam Deposition (PED), etc. for thin films and nanostructures synthesis. Indeed, unique properties can be obtained thanks to the specific characteristics of pulsed processes. One of the symposium organizers is Magdalena Nistor from the National Institute for Laser, Plasma and Radiation Physics (NILPRP).

Scope:

Advanced functional thin films require specific properties and their performances are tightly related to their composition, structure, surface morphology and interface properties which, in turn, are dictated by the film growth environment. Pulsed deposition methods of thin films offer unique opportunities to achieve higher performance products than with the continuous methods.

The symposium aims at discussing cutting edge research on pulsed techniques such as HiPIMS, PLD, PED as well as pulsed RF/DC magnetron sputtering, arc discharges and other processes for which the pulsed characteristics play a key role in the film growth. The goal is to better understand the relationship between parameters such as the high kinetic energy of film forming species, pulse width and pulse repetition rate, ionization of plasma species, transport phenomena, non- equilibrium growth, etc. and the film properties. Whatever the pulsed deposition process, this symposium aims at discussing the growth of oxides, nitrides, carbides and related thin films which cover a wide range of controllable properties. Specificities of the pulsed methods effects on thin film stoichiometry, structure and surface morphology will be addressed with particular emphasis on low temperature crystallization and epitaxy, metastable phase stabilization, self-assembled nanostructures, nanocomposites, nanosheets on rigid/flexible substrates, etc. The effect of pulsed deposition methods on the films quality and the promotion of novel or substantially improved structural, chemical, optical, electrical, magnetic, mechanical, biocompatible, bioactive, catalytic properties, etc. will be highlighted. Applications in transparent electronics, spintronics, resistive switching, renewable energy, tribology, catalysis, and sensing are meaningful illustrations of the expected results from the research carried out on films grown by pulsed methods.

Hot topics to be covered by the symposium:

• Advanced functional thin films by pulsed deposition methods with emphasis on the role of process parameters (high kinetic energy of species, pulse width, growth rate, etc.);
• Focus on the relationship between the thin films structure and physical properties;
• Oxide, nitride, carbide and related thin films for a wide range of advanced applications;
• Nanocomposite and metastable phase thin films;
• Self-assembled nanostructures, growth and novel properties;
• Low / room temperature epitaxial growth of thin films by pulsed methods;
• Van der Waals epitaxy on 2D materials and flexible substrates.

List of invited speakers:
